Answer:
Typically, Copper is used for wires in electric circuits.
Answer:
B
Explanation:
For the body to maintain stable conditions for optimal working of biochemical activities in cells, then it will require to constantly readjust any imbalances and offshoots that occur (which is the case regularly) through a positive and negative feedback mechanism. An example is blood sugar. After food intake, the blood sugars tend to rise a bit and the body produces more insulin to communicate to the cells to take up the excess glucose from the blood and store it. During starvation when the blood sugar tends to drop below normal levels, the level of insulin is reduced and that of glucagon is heightened. This causes the stored glucose to be released into the blood to restore homeostatic levels. This kind of balancing act happens with many other variables in the body.
Answer:
All of the above
Explanation:
Carbon atoms are created during the process of photosynthesis. During this process, plants will absorb carbon dioxide and sunlight to create energy, glucose, and other sugars. And for the physical changes of carbon molecules, carbon can undertake multiple changes overtime. Even though this element can be stored in the Earth for millions of years, it can be transferred in seconds from one object to another
Answer:
The correct matches are given as follows:
a. Amylase
- Starch
b. Pepsin
- Protein
c. Lipase- fats
Explanation:
The digestion can be defined as the breaking down of the complex compounds of food into simpler compounds for their better absorption. There are various enzyme that help in the process of digestion. Amylase, pepsin, and lipase are enzymes. The amylase is an enzyme responsible for breakdown of starch. The pepsin is responsible for the breakdown of protein into amino acids. The lipase is responsible for breakdown of fats.
